BUNG-BRANDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 589,231, dated August31, 1897.-

Application filed May 12, 1897.

To all whom] it mil/y concern:

Be it known that I, J AOOB FRED THEURER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inBung-Branding Machines, of which the following is a specification.

My invention pertains to a machine for branding bungs, the constructionand operation of which, together with its advantages, are set forth inthe following description, reference being made to the annexed drawings,in which Figure 1 is a side elevation of the machine; Fig. 2, an endelevation, part of the chain being removed and the pistons shown insection; Fig. 3, a top plan view, and Fig. etasectional view of thebranding-dies and the heating device.

The object of my invention is to construct a machine for branding aseries of bungs at one time and to present the bungs to the dies insuccessive series.

It also has for its object to provide means for carrying out theforegoing steps and to provide a machine simple in its construction andcertain in its operation.

In the drawings, A represents the frame of the machine, B a shaftmounted in suitable bearings therein, said shaft being provided with arelatively small pinion O, intermeshing with a larger gear D, mountedupon a shaft E, which extends through the frame. Shaft E is formed withtwo cranks F, upon which are journaled pitmen G.

H denotes a cross-bar or casting secured to the frame above shaft E andprovided with two cylindrical openings I in line with the cranks andpitmen. Within these cylindrical openings are mounted pistons,comprising a cup-shaped section J, provided with a centraldownwardly-extending lug or arm K, which enters and passes through ahollow collar L, formed upon a cup M, and a cap-piece N, to which thepitman is pivotally connected. A pin a is passed through the lower endof the arm K when the parts are assembled to prevent their being drawnor forced apart.

\Vithin the upper cup, surrounding collar Serial No. 636,187. (Nomodel.)

L and bearing at its lower end upon the upper face of cup M, is a coiledspring 0, which normally tends to keep the cups apart.

Upon each end of the frame is mounted a shaft P, upon which are mountedsprocketwheels Q Q", in line with each other and designed to receive andcarry a chain R. Said chain is composed of a series of bars S, thealternate bars being short and each bar being provided with laterallyextending lugs 19, which fit together, as shown inFig. 3. Com nectingthe lugs of the longer bars are links 0, rivets or bolts being passedthrough the ends of said links andthrough the lugs upon the bars, asshown in Fig. 3. I These links and the ends of the shorter bars formpockets or openings d, which are engaged by the teeth upon thesprocket-wheels. The shaft P, carrying the sprocket-wheel Q, hassecurely fastened to it a ratchet-wheel T and also a yoke V, carrying aweighted detent 7, designed to engage with the teeth of said ratchet andimparting motion to it under certain conditions.

To the lower end of the yokeVthere is connected an adjustable link orpitman X, which in turn is connected with a crank Y, secured upon theouter end of shaft E.

Each of the bars of the chain is provided upon its upper face with aseries of openings ordepressions 6, designed to receive the bungs whichare to be branded. Secured to the frame above the cross-bar or casting His mounted the die-holder f. Upon reference to Fig. 4 it will be seenthat this holder comprises ahollow frame g, having openings h in itsside faces, the bottom being formed by a plate 2', in Which are mountedthe brandingdies j. The upper face of the box g is provided with aseries of truncated conical openings 7a, terminating in smaller openingsZ, which communicate with the interior of the box g.

A plate m is secured upon the top of the box g and is provided with aseries ofadjustable nozzles or nipplesn, which are in line with theopenings and Z. The plate m is provided with a central opening intowhich is screwed a pipe 0, designed to be connected with a gas-supply.Surrounding this pipe 10:)

and at a distance therefrom is a pipe 17, screwed into or otherwisesuitably connected to a hood or cover 1, said hood being placed over theplate m and forming a chamber above said plate and the nipples n. Saidpipe 13 is connected by a valved laterals, through which air isintroduced in the desired quantity. The air passes into the chamher 9'and through the nipples 'n, mingling with the gas introduced through thepipe 0 beneath the plate m, the mingled air and gas finally passingthrough the openings k I and being burned in the chamber or box 9 abovethe die-holder and dies.

Upon reference to Figs. 1 and 2 it will be seen that the die-holder f asa whole may be adjusted vertically to compensate for the difference inthe thickness of the bung being operated upon or for the difference inthe height of the dies being used.

Motion being imparted to the shaft E, assumin g one of the cross-bars ofthe chain to be over the piston, the cranks F and pitmen G will elevatethe pistons and carrythe bar up against the hot dies, impressing orburning the figure upon the upper face of the bungs carried by said bar.A further rotation of the shaft will, through the connections beforedescribed, rotate the sprocket Q, imparting motion to the chain,withdrawing the bungs which have just been printed from beneath the diesand drawing the next link with its bungs into position to be elevated bythe pistons. The parts are so timed that as the pistons ascend the yokeV and its detent will be moving backward over the teeth of theratchet-wheel T into a position to again move the chain one stepforward, and this motion continues, the bun gs being presented to thedies by the piston and then being moved out from beneath the same and anew set drawn forward.

To prevent the bungs from sticking to the dies, I provide a series ofspring-fingers t, which are mounted upon a cross-bar a, secured totheframe to one side of the dieholder f. Upon reference to Fig. 1 it willbe seen that these fingers are curved downwardly and extend over thebungs, but not far enough to interfere with the proper impression of thedie upon the bun". As the chain and bungs are elevated thesespringfingers bear upon the bungs and are carried up thereby. Beingunder tension when the bungs are against the dies, when the pistonsbegin to descend the springs will exert a downward force upon the upperface of the bungs, and consequently force them from the die and holdthem in their proper position in. the pockets 6.

Having thus described my invention what I claim is- 1. In abung-branding machine, the combination of a frame; a die-holder mountedabove said frame; a bungcarrying chain mounted upon the frame anddesigned to be traversed beneath the die; and yielding mechanism forelevating the chain and presenting the bun gs carried thereby to theprinting-die.
